SOLUTION: In the case that stopped patterns are turned to a display form different from a special display form, for instance '6, 6, 7', '4, 4, 5' or '1, 2, 3', the variable time (5 to 10 seconds) of a special pattern display device 1 is shortened to shorter prescribed time (2 seconds, for instance) and such time shortening is repeated successively for the prescribed number of times (30 times, for instance). In the case that the special prize is generated before ending the prescribed number of times of the time shortening, the time shortening is ended at the point of time. |
